Application ned August 24, 1900. saranno, 27,885. ci@ man.;

resident of Chicopee, in the county of.Harnp-.

den and State of Massachusetts, have invented certain new and usefulImprovements in Extractor Mechanism for Firearms, of which the followingis a full, clear, and exact de-- scription.

rThis invention relates to improvements in itne extractor mechanism fora shotgun or other firearm of the breakdown class.

The object of the invention is to provide an extractor of entireeiciency which is composed of a minimum of very simply constructed anddurable parts,`te the end of cheapness,v ease of assemblage andadjustment, and'free' dom from derangement.'

The invention consists of the constructions and combinations of parts,all substantially' as hereinafterv fnily described,and set forth in theclaims. y,

Reference is to be had to thev accompanying drawings, in which- Figure lis Vin substance a central View extractormechanisin is comprised, thebreech being shown open, while Fig. 2 is a similar sectional view, butshowing the breech closed.

inthe drawings, A represents the frame of the gumicomprising the forwardextension A3, to which the bottom lug B ofthe barrel or barrels isjointed at d, as usnai. The bottom lng B under the barrel is providedwith the longitudinal bore or socketb, extending therethrough from endto end. rihe forward end4 p .of the bottom lug terminates at a littledis tance to the rear of the joint-pin d. -C represents the extractor orejector, the stem f of which isitted aud'plays longitudinally in theaforesaid bore b,`said stem being of a length less than that of' thesaid bored, 'bottom lug, so that the ,forward .end of the stemterminates somewhat to the rear of the to exert a crowding rearwardaction against forward end of `the bottom lng, leaving the space foroccupancy of the spiral spring g, the rear end of which is in bearingagainst the forward end of the ejector-stem, operating said stem whilethe forward end of the spring isin abutment against the vertical part hof the single piece or device D, which comprises the latch or catch forthe ejector'and also a lever extension by meansof which the said. catchhasits releasing movement imparted thereto. lower portion recessed at'z', and from this rej, which communicates with the socket or bore b. 4

This nose isformed with a screwthreadcd socket p, in whichthefscrew-plug is provided, the point or extremity of whic screw-plugconstitutes an adjustable contact member for the extension ory part 13.

s represents a limiting-pin.screw-threading through a rear-portion ofthe bottom lug and having its point entering in the groove'tiu the underside-of .the ejector-stem, this pro- `vision"serviug to prevent theextractor from being thrown out from the socket b in case the 'gunshould be broken down so far as to leave the ejector clear above thebreech'u.

sitio shown in the drawings to the position in readiness for tiring, theejector is by its impingement against the vertical forward face of thebreech and in a usual manner forwardly forced to occupy the position ofits The bottom lug has its forward The aforesaid device D is constructedin the tension 13, projecting forwardly from the upforward extremitylft'of the lower main por-l cess extends the upwardlyleading aperture,

ejector proper, C, within the 'recess o ando'r' its stem in such aforward position as to have its'catch-notch m advanced toa point aila- 0down swinging ofthe barrel also carries the forward end of the part 13away from the n pper innerend of the screw-plug q, so that the device Das a whole may havea swinging movement. from its pivotal point ofconnection with the bottom lng and as insured by the spring g incompression between the forward end of the ejector and the rearwardvertical face of the upstanding part h, so that the catch 12 will engagein the catch-notch m. Now, reversely, when the gun is broken down oropened the said integral device D, moving bodily in unison with thebarrel boty tom lug and relatively to the frame exten-l sion A2 andcoming to contact against the abutment-plug q, causes after the` gun hasbeen suiiiciently opened to render theopera- `tion of the extractordesirable the swinging of the device D relatively to the barrel-lug,whereby its catch member becomes freed from the extractor-stem, andwhereby the extractor may be projected rearwardly by the spring g.

I am aware that lit is not new in extractor or ejector mechanisms toemploy, in combination with the stem of an ejector, a' catch or latchmovable angularly to engage a catchnotch therein and aV lever jointedtothe latch and arranged to have its swinging movement imparted thereto bycontact against a xture or immovable part of the frame of the arm,`hutin such device it appears to have been deemed -necessary to coustructthe.latch and its lever separately and to so arrange or organizethepartsthat the lever has a direct- Y, abutment portion h of the device D,which performs the double duty, first, of throwing the ejectorrearwardly when the gun is opened and the catch is positively released',and, secondly, of forcing the device D into the posi- "tion to have itscatch 12 engage the catchnotch of 'the ejector when the gun is closed.

The contact-screw q may by being moved inwardlyor outwardly slightly inthe threaded socket p therefor have such a location rela-s/ f" tivelyto' the device D as to operate the latter for the release of the ejectorat any desired stage in the opening movement of the'gu.

Having'thus described my invention, what I'claim, and desire to'secureby Letters. Patent, is-- 1. In a breakdown gun, in combination, thegun-frame having at a' forward part thereof an abutment as resist-ant,the barrel having' in its bottom lug the longitudinal bore open at thefront and rear ends of said lugand having the transverse aperturej'leading to said bore, the ejector having its stein provided withacatch-notch, the device, D, comprising the bar or lever member l0having its forward end pivotally supported by the bottom lng, having atits rear end therigid upward catch extension 12, projecting within saidaperturej, havingrat a forward portion thereof the upwardlyextendingportion h constructed with the forward member 13, the end of which isadjacent said resistant or abutnient of the frame, and the spring glocated in the forward part of said bottom-lug here and operating u ponboth the ejector-stem and the said portion h of the single device D,substantially as described. A

/ 2. In a breakdown gun, in combination, the gun-frame having at aforward part thereof the screw-threaded socket p and the screwplug g adjustably engaged therein, the barrel hinged to the frame andhaving in itsbottom I thereof the Aupwardly extending kportion 7i constructed withVthe forwvrdf member 13,

over the hinge-point the end of which member is adjacent the end of saidscrew-plug q, and the spring g located in the forward partof saidbottom-lug bore and operating end- Wise against both the ejector-stem,and the said portion` h of the said single de rice D, substantially asdescribed and shown.
